摘要： A control apparatus for a multi-cylinder internal combustion engine includes pressure sensors used for acquiring combustion chamber pressure data for each engine cylinder, during each of a series of selection intervals respectively corresponding to that cylinder, with each selection interval corresponding to a specific angular displacement of the crankshaft and having a timing determined with respect to a reference piston position in the corresponding cylinder. The timing of the selection intervals is adjusted in accordance with current conditions of the engine, such as a fuel injection mode, to be appropriate for monitoring combustion conditions in the cylinders.

摘要： In an engine exhaust gas purification apparatus incorporating a LNT (lean NOx trap), during a NOx catalyst regeneration procedure for deoxidizing and removing accumulated sulfur from the LNT by producing a fuel-rich atmosphere in the exhaust system, the point at which to terminate the regeneration procedure is judged based on a difference between values of A/F ratio measured by sensors located respectively upstream and downstream from the LNT, with the regeneration being terminated when the difference falls below a predetermined threshold value.

摘要： During lean combustion, an ECU as a control device for a diesel engine calculates a ratio between a target A/F value and a detected A/F value detected by a A/F sensor, wherein the target A/F value is a ratio between a target air volume and a target injection amount in order to obtain a request torque. The ECU calculates the air volume after compensation during rich combustion by multiplying the target air volume with the compensation gain value. The ECU instructs an air intake throttle valve and an EGR valve to regulate those opening degrees according to the calculation result in order to decrease a torque difference between the lean combustion and the rich combustion.
